SPECIFICATION forming part of Letters Patent No. 784,685, dated March 14, 1905,

Application filed April 5, 1904. Serial No. 201,718.

To aZZ whom, it puny concern:

Be it known that I, J AMES M. KELLER, a citizen of the United States, residing at Los Angeles, county of Los Angeles, State of California, have invented and discovered a new and useful Improvement in Attachments for Combined Feed-VVater Heaters and Condensers; and 1 do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in attachments for combined feed-water heaters and condensers; and the objects of my improvement are, first, to construct an apparatus for quickly, conveniently, and economically condensing the feed-Water to be supplied to boil ers of engines, and, second, to purify the feedwater, reference being made to the accompanying drawings, to the figures, and the reference-numerals marked thereon.

The invention consists, essentially, in the construction, combination, and arrangement of the several parts, as will be hereinafter fully described in the specification, shown upon the drawings appended hereto, and specifically pointed out in the claims made a part hereof. I attain these objects by the construction and arrangement of the several parts illustrated in the accompanying drawings, in which* Figure 1 is a view in elevation showing the several parts connected together. Fig. 2 is a plan view of the water and oil pipes located in the upper compartment of the casing removed therefrom. Fig. 8 is a longitudinal vertical sectional view taken on the line a a of Fig. 4, and Fig. 4 is a vertical cross-sectional view taken on the lineb b of Fig. 3.

Similar reference-numerals refer to like parts throughout the several views.

The reference-numeral 1 denotes the casing inclosing parts of the apparatus, the partitionplates 2 2, the air-tubes 3 3, the oil-pipes 4 4, the feed-water pipes 5 5, the trap-plates 18 18 and 19 19, and the casing forming the receptacle 7 in the lower portion thereof for the water condensed from the steam admitted into the casing in the upper compartment 2 thereof.

The steam from the high and low pressure engines 8 and 9, respectively, or from either of said engines when used singly is conveyed by the pipe 10 into the uppermost compartment 2 of the casing 1, and the steam circu- 'lates around the oil-pipes 4 4, which are U- shaped, one end of which being connected with an oil-supply tank or an oil-pump, (not necessary to be shown,) the other end of the by the exhaust-steam or otherwise, and whenit reaches the said fire-box of the engine it is evaporized and the temperature of the oil has been elevated, thereby saving-fuel in order to raise the oil to the combustion-point thereof. The feed-water in the feed-water pipes 5 5 in compartment 2 is also heated by the steam circulating around the same, the feed-water being forced through said pipes 5 5 by means of the feed-water pump 11 and is returned again to the said pump 11, together with the water brought into the casing 1 from the spray-pipes 12 12, connected to the Water-supply system of the city or town where the plant is located. The flow of the water through the spray-pipes 12 12 into the casing 1 is regulated by means of the float 13, the rod 14, and the valve 15 within the pipe 12 on the outside of the casing 1. 1V henever the water in the receptacle 7 in the lower portion of the casing 1 is decreased in quantity, the float 13 drops, the rod 14 descends and opens the valve 15, and the water from the said supply system passes through the spray-pipes 12 12 into the casing 1 until the requisite quantity of water has accumulated in the receptacle 7, when the float 13 again elevates the rod 14 and closes the valve 15 and stops the spray or water from entering the casing 1. The receptacle 7 in the lower portion of the casing 1 is connected with the cylinder 16, in which the float 13 is operated, on the outside of said casing 1 by means of the pipe 17 through which water in the receptacle 7 is conveyed into said cylinder. The exhaust-steam from the said engines passes from the compartment 2' in the top of the casing 1, first circulating around the said oil-pipes 4 4, then around the feed- Water pipes 5 5, and travels to the farther end of the casing 1 and falls over the end of the 1' artition-plate 2 between the end thereof and the inner surface of the casing 1 through the passage-way 6. From the compartment 2 the steam enters compartn'ient 2, travels to the opposite end of the partition-plate 2, separating the two uppermost compartments, and there circulates around the air pipes 3 3, located in said compartment 2. From the compartment 2 the steam condensed and the spray pass into compartment 2', from thence into compartment 2, from thence into compartment 2 and from thence into compartment 2, and from this last-mentioned compartment the condensed steam and spray fall over the end of the lowermost partition-plate 2, between the end thereof and the inner surface of the casing 1, through the passage-way 6, into the receptacle 7 in the lower portion of said casing.

To the lowermost partition-plate 2, on the under side thereof, depending vertically downward therefrom, I secure in any suitable manner downwardly-proiecting trap-plates 18 18, and to the bottom of the casing 1 in the receptacle 7, projecting vertically upward, I secure in any suitable manner the trap-plates 19 19. The said trap-plates 18 18 and 19 19 in the receptacle 7 of the casing 1 form traps by means of which the oil taken up by the steam, used for lubricating portions of the piston, piston-head, and other parts of the engine, found mixed with the water condensed from the steam, is, drawn off through a suitable overflow-pipe (not necessary to be shown) from the surface of the water in the receptacle 7.

The casing 1 may be thoroughly washed out by opening the valve 15 in the pipe 12 on the outside of the casing 1 and the valve 20 in the drain-pipes 22 22, connected to the bottom of the receptacle 7 on the outside thereof by means of the handle 21, thus permitting; the water from the said water system to How through the casing.

The passage of the steam and vapor from the compartment 2 of the easing into and through all of theintermediatc compartments in a serpentine course into compartment 2, and, lastly, into the receptacle 7 at the bottom of the casing 1, is augmented and materially hastened by means of my pneumatic apparatus, the air-pump 25, and pipe 26, leading from the lowerportion of the casing 1, preferably from the lowermost of said compartmentsthat immediately above the receptacle 7-to the said air-pump. By means of the said airpump 25 and connecting-pipe 26 and the condensation of the steam a vacuum is created in the casing, the capacity of the condenser greatly increased, the engine or engines relieved, and time and labor saved. By means of the fan or blower 30, operated by the engine 31, micontaminatcd pure air is forced through the air-pipes 3 3, located in the said compartment 2, to and including compartment 2', heated by means of the exhauststeam or condensed hot water from the exhaust-steam circulating around said air-pipes, and emerges from the opposite ends of said air-pipes into the hood 33, located at the opopsite end of the casing 1 from .that to Which the said fan or blower is attached. The pure heated air is conveyed from the hood 33 by means of pipes, lines, or chutes to parts of the building in which the plant is located or may be carried to other buildings desired to be heated.

It is obvious that many variations and changes in the details of construction and arrangement of my invention would readily suggest themselves to persons skilled in the art to which it appertains and still be within the scope and spirit of my improvement.

I do not desire to confine this invention to the specific construction, combination, and arrangement of parts herein shown and described, and the right is reserved to make all changes in and modifications of the same as come within the spirit of this invention; but I do desire to secure as my invention all features of construction and equivalents thereof that come within the scope of my improvement as herein shown and described, and illustrated upon the drawings appended hereto.
